Re: LAPTOP KEEPS SHUTTING DOWN

I have the same computer as you but I have AMD (I'm guessing yours is intel). Anyway, ended up happening to me and I sent it in. So far they have replaced the system board, hard drive and CPU and it's still not working.

Re: LAPTOP KEEPS SHUTTING DOWN

My laptop is a Toshiba Satellite L555D-S7930. I started having the same problem about a year after I got it. When looking into it, I saw the the fan vent was clogged up with dust and cleaned it out. I cleaned and replaced the heat sink compound on the CPU and Video Chip. I also updated the BIOS. It still has issues. I do know that is an overheating issue. If I set it up on its side and place a floor fan next to it (blowing into the vents on the bottom), it remains on. If I boot it up without the floor fan blowing on it, it stays on for a minute. It then shuts off (I think) right after the cooling fan shuts off.

As far as I know Dells don't have a video processor. The Toshiba L555 does. The L555 has a heat sink on both the CPU and the Video Processor. I'm guessing that the Toshiba puts out more heat the your daughter's Dell.
